The owner of a head shop and hookah lounge in downtown Bangor is facing federal drug and money laundering charges.

Christopher Ruhlin, 48, of Holden, owner of Herbal Tea & Tobacco, located at 44 Main St., and his employee, Terrence Sawtelle, 48, of Bangor, were indicted Sept. 14 by a federal grand jury on one count each of conspiracy to manufacture and distribute marijuana.

Ruhlin, who has owned the shop since 2011, also was indicted on two counts of maintaining a drug-involved place and seven counts of structuring bank transactions to avoid reporting deposits of $10,000 or more to the U.S. Department of the Treasury. The government also is seeking to seize the Frankfort and Bangor properties where marijuana allegedly was grown and sold and the cash Ruhlin allegedly made selling pot.

Agents with the U.S. Drug Enforcement Administration seized about 400 marijuana plants, 295 marijuana root bulbs, processed marijuana, receipts from a garden center totalling about $25,000 and other items on May 12, 2016, when they raided property on North Searsport Road in Frankfort where Ruhlin allegedly grew and obtained marijuana, according to court documents.

Three months later, 23 containers of processed marijuana were seized from the 13 Owls Club smoking lounge, adjacent to Herbal Tea & Tobacco, court documents said. Ruhlin is not licensed with the Maine Department of Health and Human Services as a medical marijuana caregiver, court documents said, but his lounge offered a space for patients to smoke outside of their homes, which has been legal since 2013.

An affidavit for one of the search warrants cited a Dec. 15, 2014, Bangor Daily News article about the opening of 13 Owls Club: “The smoking lounge does not sell or provide medical marijuana, Ruhlin stressed, adding, ‘you can bring your own.’”

The indictment was unsealed Friday after Sawtelle was arrested and made his first court appearance. He pleaded not guilty to the conspiracy charge and was released on $5,000 unsecured bail.

Sawtelle’s attorney, David Bate of Bangor, declined to comment on the case.

If convicted, Ruhlin and Sawtelle face up to 20 years in federal prison and a fine of up to $1 million on the drug conspiracy charge, the most serious charge.
